Pediatric emergency physicians are experienced in the diagnosis and treatment of all types of emergencies in infants, children, teens, and young adults. They usually treat the following types of emergencies:
Solar irradiance. It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Indeed, studies show that solar variability has played a role in past climate changes.
Other human activities include agriculture and changes in land-use patterns. They all work to tip the Earthâs energy balance by trapping more heat. Even scientists who think human activity is the main cause of climate change don't deny that natural changes will cause temperature fluctuations on Earth. However, their argument is that in the current cycle of climate change, the impact caused by man is far greater.
